AndrewPH Posted August 18, 2020 With the recent release of 1.1.9, I urge all users to start using it. Some time this week I'll be switching on 2-factor authentication for all users, and the older clients don't have the code needed to handle the 2-factor challenge. If you use ClassiCube on Steam, you should already be on 1.1.9 - I made sure to update that 😛 Currently about 35% of the active playerbase per day uses 1.1.8 or older. Share this post Link to post
